Application-med Iay 3, 1912. Serial No. 694,987.

To 'all 'wiom t may concern# Be itknown that I, GEORGE C.'HARVEY, a.citizen of the United States, residing at Geneva, in the county ofAshtabula and State 1 of Ohio, have invented a certain new A and usefulImprovement. in l Concrete Struc tures, of which the following is afull, clear, and exact description.

This invention relates to concrete structures, vand the object of theinvention is to provide a concrete structure formed ometal-reinforcedblocks, the -metal rein-y forces being so constructed and .arranged I-that they may readily be interlecked when laid to form a tying orbonding engagementv between each block of a course of blocks, and alsobetween each successi-ve course of blocks, to thereby producea firm anddu rable structure. 0

The invention vconsistsl in a concreter structure, having as itsessential novelty a series of blocks, each of said blocks having groovedends, and provided with a number,

of longitudinalV reinforcing rods molded therein and having their endsprojecting from the ends of the blocks and extending into the groovedends thereof and'provided with bent orvhooked ends arranged so that thehooked ends of the rods of adjacent blocks may readily be interlocked;each of said blocks having a substantiall centrally arranged reinforcingrod embed ed therein and engaging the longitudinal rods therein andprojecting vertically from the upper surface of the blocksland adaptedto enter theV space between the adjacent grooved ends of the blocks'ofthe course above and interlock with the hooked ends ofthe longitudinalrods, all substantially as I will proceed now moreparticularly to setforth and finally claim.

In the accompanying drawings illustrating the invention in the severalfigures. of

which like parts are similarly designated, Figure 1 is an elevationartlv 'broken away transversely and vertica` and showing myY inventionembodied in a silo. Fig. 2 is a.

transverse-horizontal section taken' in the plane of liiie '2V-2, 1.vFig. 3 is a perspective view of a block. Fig. et is a. transversevertical section of a. block taken in the plane of line 4--4, Fig. 5.Fig. 5 is .a Vvertical section illustrating parts of two courses fofblocks. F' 6 is'a transverse horizontal section throng the door and itsadjacent -tively at 11 so far as the forni 4of the silo is concerned, itmay be as usual, and using the silo I also be made of mortar ornement 8,all as indicated inFig.v l. I

The several blocks 6 may alike in construction, and theywill be ofappropriate shape or shapes and size or sizes. for the structure tobe'erected. As shownin-"the drawings, each block is segmental, and itsends are provided with Aver. tically disposed grooves ,9. Molded in itsbody are `the longitudinally disposed reinforcing rods 10 of metal,these rods extending outwardly into thegrooves and bent transversely andvertically at their oppositeends, respectively, as indicated respecand12 to form complemental interlocking hooks, so that when two blocks arearranged end for end their rod ends or Vhooks 11 and 12 will interlockand 'thus serve to' tie the' blocks together. At about the longitudinalcenter of each block is a vertically disposcdrod -13 permanentlyeinbedded in the block and connected with the longitudinal rod or rodsin any suitable way, as by bending its end lll around the lower-most-rod 10, or by forming such end as an eye through which the longitudinalrod is extended. This vertical Vrod is so disposed as to intersect thehooked ends 11 and 12 of adjacent blocks in the course of blocks nextabove where the joints break, thus not only serving to retain these ends11V and 12 vin an interlocked--state, but also :serving to prevent theblocks from getting out of alinenient transversely as welllongitudinally. The spaces between the vedends of'the blocks occupied bythe hookedends'll and 12 of the longitudinal rods and the projectingends 13 of the vertical rods may also be filled with mortar or cement asindicated at.15, Figs. 1 and 2.: In the making of a. doorway, there maylbe substantially be blocks having their llongitudinal rods l threadedand bolted in the door-jambs 16, as shown in Fig. 6. Thesedoor-'ambs mayhave the ladder rungs 17 bolted in them; and they may be provided withyguidegrooves 18 Vto receive sliding door sections l 19 in any usual orapproved Way.

Correction in Lettersl Patent No.f1*,050,130.

As already suiciently indicated, the blocks will be' in size and shapeappropriate to the structure to be erected. They may be made of cementor concrete,- or other suitable plastic material lor composition. 1 s

What I claim is l. A building block for concrete structures, havingvertical grooves in o poste ends, longitudinally arranged rein orcingrods molded in sald block and projecting into the grooves andtenninating-therein in hooks, Vthe hooks upon opposite end s of theblock being arranged so that thehooks and adj acent'blocks willinterlock one with the other when the `blocks, are laid end for end, anda vertically disposed lrod embedded [senin] in saidblock and' projectingthrough the 25 block aboutfmidway and connected 'to and anchored by oneor more of said longitudinal rods.

Y 2. A concrete structure, composed of.'

blocks laid end to end in courses with.` break-joints, the blocks havingvertically disposed end grooves, and longitudinal rel inforcing rodsmolded in said blocks'and having complemental interlocking hooked endsprojectlng into said grooves, an'd vertically disppsed rods embedded inthe blocks and tied tothe longitudinal rods and projecting through theblocks and into the grooves of adjacent superposed blocks and adapted tosecure the vengagement of the interlocked ends of the longitudinal rods.

In testimony whereof I have hereunto set my hand this 2d day of May, A'.D. 1912.
